A CASE OF METASTASIS OF RENAL CELL CARCINOMA TO THE SMALL INTESTINE DETECTED BY SINGLE BALLOON ENDOSCOPY

Abstract

A 53-year-old woman underwent right nephrectomy for renal cell carcinoma in April 2009. She was found to have anemia around April 2010, but no source of bleeding was identified by gastroscopy or colonoscopy. Since small-bowel bleeding was suspected, single balloon enteroscopy was performed in July 2011, and four type 2-like lesions with submucosal tumor-like elevation were detected in the jejunum. These lesions were diagnosed as small bowel metastases from renal cell carcinoma by biopsy and partial enterectomy was performed.
